Abstract
Organofunctionalized montmorillonite clays (MM) have been prepared with ammonium cations having a distribution of alkyl chain lengths. Relative to clays treated with alkylammonium cations having no distribution of chain lengths, the ultimate tensile stress of the epoxy-based composites increased. Also, depending on the preparation of the functionalized clays, an increase in the strain-to-failure is also noticed. The tensile stress and strain-to-failure of the organofunctionalized clays are compared to neat epoxy. The epoxy matrix chosen consists of diglycidyl ether of bisphenol A (DGEBA), 1,4-butanediol diglycidyl ether (1,4-BDE) and cured with meta-phenylenediamine (m-PDA). All MM composites were prepared using 5 mass % loading of the organomodified clay. The goal of this research was to compare the impact of surface treatment on MM clays that were used in the preparation of epoxy-based composites.Proceedings Title
